Primary signal detection using distributed machine learning in multi-area environment

Abstract

Methods and systems for primary signal detection using distributed machine learning in a multi-area environment are disclosed. In an example method, it is determined that a first user equipment (UE) device moved to a first predefined area from a second predefined area. A controller sends, to the first UE device, a first machine learning model configured to detect an anomaly in an RF environment associated with the first area. The first machine learning model may have been determined by a second UE device associated with the first area. The controller receives, from the first UE device, anomaly data indicative of an anomaly detected by the first UE device via the first machine learning model. The controller may optionally determine that a primary signal is present in an RF environment associated with the first area based on the anomaly data from the first UE device.
